[1]} proposed a toy model to explain the puzzling light curve of the LSNe SN 2018don. SN 2018don is a hydrogen-poor LSN that has a sharp drop in its light curve [2]}. It has a long rise time to maximum light relative to other LSNe [3]}.
[1]} built simple bipolar ejecta models for jet-driven CCSNe and showed that for an observer in the equatorial plane of the bipolar morphology the light curve has a rapid luminosity decline, and even an abrupt drop. In some cases there is no abrupt drop, but rather a `knee' in the light curve where a rapid drop changes to a moderate drop in luminosity. [5]} proposes that such a bipolar explosion might explain the `knee' in the light curve of the SLSN SN 2020wnt (for its properties see [6]}, [7]}, [8]}).
